摘要： Optical loop-back is provided within an optical restoration system of an optical communication network. According to one embodiment, an optical restoration system includes first and second spare optical links (also called restoration paths) optically coupled in parallel between first and second optical cross-connect switches. Each restoration path includes a light regenerator and an optical amplifier. First and second optical cross-connect switches are each switched to provide respective optical loop-back paths between the first and second restoration paths or spare links. In one example, the optical loop-back paths can be configured within the optical cross-connect switches. In another example, the optical cross-connect switches are configured to couple optical signals between an external loop-back coupler and the first and second restoration paths or spare links. According to another embodiment, the first and second optical cross-connect switches are each switched to provide respective optical loop-back paths between different WDM channels in a bidirectional restoration path or spare link. In one example, the optical loop-back paths can be configured within the optical cross-connect switches. In another example, the optical cross-connect switches are configured to couple optical signals for different WDM channels between an external loop-back coupler and the bi-directional restoration path or spare link. Through loop-back connections, optical signals from light regenerators can travel along an idle restoration paths to squelch false alarms by light regenerators and to keep the optical amplifiers stabilized. Through loop-back connections, optical signals from light regenerators can also travel along a working path to squelch false alarms by light regenerators and to stabilize optical amplifiers in the working path prior to normalization.

摘要： Methods, systems, and devices are presented that allow a wireless communication device (WCD) to use multiple access identifiers (NAIs) in conjunction with a communication session between the WCD and a home agent. The home agent may maintain a binding that reflects the state of the session. Accordingly, the binding may contain a home IP address (HOA) as well as a first NAI. The home agent may then receive a registration request message containing the HOA and a second NAI. In order to avoid potential hijacking attacks from entities other than the WCD, the home agent may, in conjunction with an authentication server, attempt to validate that that first NAI and second NAI are both associated with the WCD. If this is the case, the home agent may update the binding to reflect that the second NAI is associated with the session, and the home agent may maintain the session so that the WCD does not suffer an appreciable interruption in service.
摘要翻译： 呈现允许无线通信设备（WCD）与WCD和归属代理之间的通信会话一起使用多个接入标识符（NAI）的方法，系统和设备。 归属代理可以保持反映会话状态的约束。 因此，绑定可以包含归属IP地址（HOA）以及第一NAI。 然后，归属代理可以接收包含HOA和第二NAI的注册请求消息。 为了避免来自WCD之外的实体的潜在劫持攻击，归属代理可以与认证服务器一起试图验证第一NAI和第二NAI都与WCD相关联。 如果是这种情况，则家庭代理可以更新绑定以反映第二NAI与会话相关联，并且归属代理可以维护会话，使得WCD不会在服务中遭受明显的中断。

摘要： A coupling between an optical fibre (1) and an opto-electronic device e.g. a semiconductor laser (2) is located within a hermetically sealed housing (3,6). The device is supported on a header (14) mounted on the front wall (3) of the housing, the lead (16) to the device passes through the housing wall via a glass-to-metal seal (17,19,20), and the fibre is soldered into a ferrule (10) which is inserted through a boss (4) on the front housing wall. After alignment of the fibre with the device, the ferrule is clamped in position by two parallel sets of screws (11(a), 11(b)) inserted through the boss, and is then soldered to the boss. The housing, header, ferrule and metal component(s) of the glass-to-metal seal are all formed of the same metal, preferably gold-plated copper, to avoid differential expansion.

摘要： A Mach Zehnder interferometer with arms of equal length is formed between two optic fibres. This is achieved by locating the lightly tensioned fibres in a generally parallel configuration and forming optical couplings between them at points which lie on the center-line of the configuration. Preferably the couplings are formed by a fused biconical tapering technique.
